Specification of Letters Patent.

Patented Dec. 9, 1913.

Application filed May 20, 1912. Serial No. 698,386.

To all whom it may concern:

Be it, known thatI, ALonzo A. WAnNnn, acitizen of the United States, anda resident of New Britain, in the county of Hartford tion of a toasterembodying my inventions Fig. 2' is an end- View with parts be ng.

broken away to show construct-ion. Fig. 3 is a sectional plan view of aportion of the device taken on the line a: of Fig. 1. Fig. 4 is asectional side view of the parts shownin Fig. 3.

Referring to the drawings a denotes the base which is preferably made ofsheet metal provided at its ends with feet in the form of disks 2located between the outturned ears 3 and secured by the pins 4. Thedisks may be notched as at 5 so as to project slightly above and engagethe edge of the base. This is an inexpensive and extremely satisfactorystructure for finishing the base and providing suitable foot pieces. Ifdesired, these disks can be made of insulating material.

On the base is secured a standard 10 formed from sheet metal and whichconstitutes the support for the toaster proper. At either end of thestandard a lip 11 is turned up. The frame 15 of the toaster is ofinverted U shape with its side arms lying against these upturned lips11. Fitted against the inner faces of the side arms of the frame areplates 16, 16 secured at the top as by the screws 17, 17, slotted alongthe median line as indicated at 18, and preferably corrugated at thispoint as clearly seen in Figs. 3 and 4: The ends of the frame arms andthe lower ends of these plates are secured to the lips 11 by the clamps12 and screws 13, binding the structure together and of a wire coiledabout acore of insulating material. The cores which are the same in eachsection of the unit can conveniently be made of layers of mica 22stifl'ened by a strip' of metal 23 passing centrally through thembetween the layers. The ends of these cores are seated in the grooves 18in the plates. 16, and by corrugating the plates in the grooved part, adeeper bearing for the ends of the cores is secured as clearly seen inFigs. 3' and 4.

The sections of the unitsare arranged one above the other spaced apartslightly and connected together by the links 34. The resistance wire 25is wound more closely on the lower section 20 than is the resistancewire 35 on the intermediate section 30, which in turn is more closelywound than the resistance wire 45 on the upper section This may be onecontinuous wire starting at one terminal and wound' successively uponthe separate sections, and then brought back to the other terminal 51,or they may be separate wires joined together in some convenient way.This is not material so far as certain features of the invention areconcerned.

Guard wires pass through apertures in jthe top of the frame, and theirends enter apertures in the standard; This keeps the bread, or othermaterial, from lying directly against the unit and so prevents burning.;Holders 56, 56 are pivoted on cross bars 57 near the bottom of thetoaster and are pressed by the springs 58 against the frame Theresistance as illustrated is in the form with the result that they holdthe bread closely against the guard wires. These holders canconveniently be made by bending up a wire to shape, as clearlyillustrated, providing it with the inturned projections 59 to receive across bar (30 made'of sheet metal with portions folded over at each endto keep the material evenly pressed against the lard wires. A base 61attached to the sides of the holder forms a bottom support for thematerial which is being toasted. A top 70 is provided with dependingspring arms 71 channeled at their ends to slide on the frame, andapertured to receive the heads of the screws 17 which constitute holdingand positioning devices. This top prevents the too rapid escape of heat,and can conveniently be used for keeping toast and other materials warm.

WVhile I have described the illustrated embodiment in. detail,nevertheless I do not wish to be understood as limiting myself to v theexactconstruction shown and described,

but on the contrar desire to claim protection'for any modi cations whichmay come within the spirit of the invention.

I claim as my invention 1. In a device of the character described,

a base, a frame supported thereon, a sectional heating unit mounted inthe frame, the sections of said unit being of similar shape and arrangedclosely together edge to edge in the same plane, with the adjacent edgesof said sections'approximately parallel, and means for electricallyheating the lower part of said unit to a greater extent than the u perpart thereof.

2. In a evice of-the character described, a base, a frame mountedthereon, a sectional heating unit supported in said frame, the 'sectionsbeing arranged one above the other in the same lane with their adjacentedges arranged c osely together and approximately parallel to oneanother, said sections comprising cores of insulating material with aresistance wire wound thereon, the number of turns of said resistancematerial on the lower section being in excess of the number of turns ofthe resistance material on the upper section.

3. In.a device of the character described, a base, a frame supportedthereby the sides of said frame being longitudinally corrugated andslotted in the top of the corru ation, and a heating unit comprising ain wide core whose ends are adapted to fit within the slots and aresistance material mounted on sai core.

4. In a device of the character described,

a. base a frame of inverted U-shape having its sid e arms secured tothebase at their ends, longitudinally corrugated and slotted platessecured to the inner faces of said side arms, and a sectional heatingunit supported I in said frame, said sections being arranged one abovethe other, and each section comprising a thin wide core whose ends areadapted to fit in the slots and resistance material mounted on the core.

5. In a device of the character described, a base, a frame ofinvertedU-shape having its side arms secured to the base at their ends,longitudinally corrugated and slotted plates secured to the inner facesof said side arms, and a sectional heating unit supported in said frame,saidsections being arranged one above the other, and each sectioncomprising a thin wide core whose ends are adapted to fit in the slotsand a resistance Wire wound upon said cores, said wire being wound moreclosely upon the lower core a than upon those above it.

6.. In a device of the character described, a base, upturned li s at theends thereof, a frame of inverted -sha e having the ends of the sidearms locate means for clamping said arms to said lips,

against said lips, i

and a heating unit supported by, said frame.

7. In a device of the character described, a base, u a frame of invertedU-shape having the ends of its side arms located against said lips,

plates secured to theinner faoes'of the side arms, clamps to secure saidplates and arms turned lips at the ends thereof, 1 I

to said lips, and a heating unit-supported in said pla ALONZO A. WARNER.Witnesses:
